Please allow me to retort. There are fewer and fewer people turning wrenches on these older model bikes, the old timers (the guys that were in their prime when there was still a million of them on the roadin the 90s) are either retired, dead or now maintaining their new efi touring bagger (most not all) so here on a specific forum is the absolute best place for me to get the info on a 24 year old bike. Warren, I have no reason to pull the carb. I never said i had a running condition. I dont. I only wanted to know if there was a discernable difference between an s.e. carb and factory oem because i'm sure somewhere down the road I will be doing a rebuild. The ethanol will eventually goo up or break down something inside that fuel sys. So because of the sticker on the airbox it made me curious...obviously im not that familiar with them to be able to tell the difference. that's why i'm here picking the brains of you that are still out there running and repairing these EVOs.
I do have the factory service manual issued in 1995 it has one small pic of an odd shaped air filter and the pic of the carb is a drawing of how it works....Have you seen the diagrams and pictures??? The book is perfect for the intended application if the bike has all its oem parts on it......the internet yes is a very useful tool but not always correct when looking for pics of an unknown item. I guess I should have been more clear and asked the question. "if side by side how can I tell the difference of a stock carb and an aftermarket?" (Eg. the choke lever is on the base of the s.e. carb when the factory has the primer pull **** on the left under the tank. or the Oem has a plastic inlet nipple when the others are pressed aluminum)
I've been part of many forums over the years from JEEP, F150, 1300 and 1800VTX, and a few different Boat sites. I have now graduated to Harleys. our current rides
Yes, the better the quality of question, or the more specific it is, the better the quality of an answer is possible.
A parts book would be useful addition to your workshop library, or just go to one of the online fiches and print out all of the pages. It clearly shows the stock airbox/filter configurations. I find them more useful than workshop manuals.
A Screamin' Eagle 40mm carburetor (p/n: 91731-85 to 91731-88) is a separate issue from just a Screamin' Eagle air filter kit ... but it was pre-1989 and the CV Kehein carb you likely have.
There was also a Screamin' Eagle Pro Big Bore 44mm CV (27934-99). I've never actually seen in one real life, but it looks the same at the stock CVK. Also a 42mm flatslide carburetor from Mikuni. There was even a 51mm CV (but god knows who needed them) and aftermarket carbs from S&S and others, so in all fairness, how were we supposed to know what you had without pictures?
So one thing you did learn from all this is each element - carb, manifold, filter etc - comes separately and is customizable separately.
Donny Peterson wrote a Bible size book about Evolutions that is very historical if you are interested in getting into them. It's not great from a performance or mechanical point of view but has lots of such data.
Here's what a similar kit would have looked like new. The chrome cover is an original stock item.

Hehe Warren…Thanks for the pic..YOU were the guy I was looking for on here! You can look at a pic and tell whats what.....That was the kind of info I was looking for! I'm like that with Outboards. My whole career turning wrenches in the boat industry! I can look at a pic or hear the sound of one running and tell you what manufacture it is, if its running correctly and(if pic is good) if theres non oem parts on it.....I appreciate all the info. yes I will invest into a parts book, thank you.....
Now you opened the can of worms for me. Oil pump/timing cover???...here we go!
Yeah, I used to be like that but like to think I retired my OCD on it a little and have not kept uptodate. I think you'll find that there any many here better than me at it.
You'd be looking for numbers and letters on the nose of the cam, or may be first lobe, if the seller does not know.
If it's an 'N', get ready to chuck it in the recycling and replace it with a real one.
I'm leaning towards a chrome oil pump cover but I can't see the details from the scale of photo. Obviously he stuck a braided steel oil line on, it which made me think he had invested himself in making the engine better. Nice original details such as the 5 speed sticker. Looks like you have the original headers with the balance pipe, that's a good thing.
For what it's worth, I've a growing affection from old hand crankable Volvo Penta MD engines. They remind me of the simplicity, and lope, of old H-Ds. It's just a shame there's not the aftermarket producing cheap parts to keep them alive. Hell, who needs electrics and more than 2,300 rpm?
ah the old Volvo penta! Swedish precision! they were excellent . I was a kid when I started working at a marina .....I learned how to adjust points and set dwell etc. on a good amount of older boats..... we had a 29chris-craft with a crank to start 4cyl. Very low compression thankfully
I met a guy with a rigid 60s chopper panhead with a kick and also an electric aftermarket starter......its been sitting for about 25years( pretty rough shape) hes thinking of selling it.....asking 4k....i'd love to get it running again.

Reason: wrong engine

Yeah, a 15hp engine that weight 420lbs. They knew how to build them back then. A rep once said that if they were to build them to the same standard today, they'd cost about $20,000.
The shame is for the lack of spare parts, so many are just become mooring blocks. There's not even any money in scrap cast iron these days.

My mistake john....its a panhead....I had to edit my post....if it was a knuckle I would have ran to the bank and drained the saving account that same day
